for preventing the injurious accumulation' of mineral or base products; and to provide simple and eflicient mechanical means for accomplishing the. objects stated.

DrawingaFigure 1 is a vertical longitudinal section of a still constructed and arranged in accordance with the present invention, the section being taken as on the line V1--1 in Fig. 3 Fig. 2 is a longitudinal section on an enlarged scale, the section being taken as on the line 2-2 in Fig. 3; Fig. 3 is a cross section on an enlarged scale, the section being taken as on the'line 3-3 inv Fig. 1; Fig. 4- is a detail view on an enlarged scale -showing one of the tube-scraping disks with which the still is provided.

Descptz'ofm-The herein described still is employed principally for the reduction of crude or heavy oils wherein the lighter volatiles may be liberated by whatv isv known as destructive distillation, or by breaking down the constitution of the original material. To

this end it is desired that the oil Should be., subjected to heat for a predetermined period,

and that the vapors should be collected and recovered by condensation after the' heavy or base particles have been removed 'and permitted to settle. With this object in view, the heating domed chamber 9 is interposed between the fire box 10 and the smoke tine 11, from which extends a pipe 12. The

f chamber 9 is provided, at the upper and lower ends' thereof, with arches 13 and 14,

which arches are formed from refractory material, which material is also used fgr lining the box 10 and line 11, as seen best 1n l Fig. 1 of the drawings. Between the box 10 and flue 11, isplaced a fire wall 15, also constructed from-refractory material and supported by the arch 14. The wall15 extends completely across the chamber 9 and compels the heated gases delivered from the box 10 to pass upward through the said chamber before being ,delivered therefrom to the Hue 11.

The oil treated in the'present still is pri- 'l marily delivered from a supply to a receiving tank 16. The tank 16 is suspended in a chamber `17 below the arch 14, and so removed from the influence of the heat generated in the box 10. -The tank 16 isthus suspended by pipes 18, which extend through suitable perforations in the arches 13 and 14 and are bolted to short nipples 19 screwed or otherwise rigidly secured in a delivery `l tank y20 above the arch 13. The tank 20 rests f f V forming part of the furnace structure in directly upon the supporting'iangle..irons 21,

which is incorporated the box 10, flue 11, and chamber 9. The pipes 18 are provided at the ends of each, with bolting flanges 22, which are secured to bolting flanges 23 and 24 formed on the nipples 19 and 25,'the"lat' ter being rigidly secured in the tank 16,

When the flanges above enumerated are securely united, it willbe found that the .tanks 16A and 20 and pipes 18 yconnecting the same, are supported upon the angley 1rons 21, the said tanks being protected from thel hot gases in the chamber 9 while the pipes 18 communicating between the two tanksv are directly subjected thereto.

The tank 16 receives the by supply pipe`26. The oil is supplied to the tank 16 under. pressure, thepressure being produced and regulated by any suitable .and conventional means. `As seen best in.

Fig. 1 of the drawings,`the oil is delivered to the tank 16 near the top thereof. In this manner, provision is made for .the precipitation or separation of the residuum, coke or carbon contained in the oil or resulting from oil'for treatment i the treatment thereof while passing through the tank 16 and settles therein to the bottom thereof. To remove the residuum above mentioned, a manhole having a cap 37 is rovided.

The tank 20 collects the lighter elements of distillation and is provided with a series of gage cocks 28 and a dome-29 from which the lighter vapors or volatiles are carried oft' by a pipe 30. The pipe 30 is inclined and passes through a water-coolin jacket 31, where thevapors or gases are su cientl condensed to descend the pipe 32 to the rad1 ating coils 33, which Aare mounted in a coo ing bath 34 of conventional form and construction. The coils 33 and bath 34 are a1- the pipes 18. This residuum is returned to roo ranged to condense the gases and cool the liquid delivered by the pipe 32, which are delivered thence by a pipe 85, to a separating drum 36. vlFrom the drum 36, finished oil is passed for. removal by way ofthe gage 40, while the residuum is drawn from the drinn by the pipe 38, the delivery of the carbon products being controlled by the valve 39. Pipe 37 leads to a pressure gage. The sight gage 40 is connected with the drum 36 for ascertaining the quality of the product delivered thereto from the still, said gage having a transparent panel 41through which the passing liquid therein may be viewed. The crude or heavy oil delivered to the tank 16, is lifted therefrom to the pipes 18. Suiiicient heat is generated in the box 10 and chamber 9 to break down the oil for separating the lighter and more gaseous elements from the base elements.

It becomes necessary, in order that the pipes 18 shall not be clogged, to remove the coke. To accomplish this, there is employed in each pipe 18, a vibrating rod 42. The rods 42 are suspended in pairs, the members of each pair being suspended by a connecting beam 48. The connecting beams 43 are each rigidly mounted on a rocking shaft 44 disposed within the tank 20 and supported therein by a bearing standard 45 adjacent one end of said tank and a stuling box 46 disposed at the opposite end of said tank. The shaft 44 extends beyond the stuiing box and is provided with a crank handle 47 to be employed for rocking the said shaft either manually or by means of power machinery of any conventional and approved type. To maintain the straight-line arrangement of the rods 42, braces 48 are extended lengthwise of the tank 20.

At intervals e -ualing somewhat less than the stroke of t e rods 42, are disks 49, which slidingly t the pipes 18, bearing lightly against the inner surfaceI thereof to maintain the same clear of foreign deposit. The disks 49, as seen best in Fig. 4 of the drawings, are provided with a series of perforations 50, through which the oil passes as the disks and their rods are raised and loweredl in said pipes. A mechanical agitation is thus imparted to the columns of oil in the pipes 18, which materially assists in the disintegrating action of the heat to which the oil is subjected in the pipes 18, and when passing from the tank 16 to the tank 20. While the perforations 50 permit the passage of `oil upward therethrough, they also serve as means for the passage downward through the pipes ,18 of the carbon deposit or other residual or heavy matter eliminated from the oil under treatment. As above stated, this heavy material is removed from the tank 16 through the Jmanhole 27. A certain proportion of heavy oil also settles in the tank 16, and this may be drawn ofil by the pipe 51. It will be noted that the construction employing the pipes 18 for suspending the tank 16, provides for preventing buckling of the said pipes, the weight of the tank 16 being sufficient to maintain the straight-line arrangement of said pipes.
